How Far Does the Fermi Level Move When You Dope Silicon?
Each tenfold rise in doping moves silicon's Fermi level by 59.5 mV, since EF − Ei = kT ln(ND/ni): 0.347 eV for 10¹⁶ donors. Worked numbers, limits and mistakes.
Why Does a Zener Diode Hold Its Voltage, and When Does It Stop?
In breakdown a Zener's current can swing widely while its voltage barely moves, but only above a minimum. A worked regulator design shows where it stops.
How Many Flip-Flops Does a Mod-N Counter Need?
A mod-N counter needs ⌈log₂N⌉ flip-flops: 4 for mod-10, 7 for mod-100. Why ripple counters pass through wrong counts on the way, and how to read them safely.
